It exposes information of the object in terms of Properties, Attributes, Events, etc. Row though the basic usage of TypeDescriptor is to get metadata of an example, yet it also exposes features to extend the object on the fly. Let us now form few capabilities of Descriptors with a little information about its usage. TypeDescriptor is used to get information of a Type. To use it, swxchat need to pass a ace to its static methods..
At each next octave, the resolution of the images is halved to save computations. The images composing the Gaussian and DoG scale space can then be arranged as in the following figure:. Notice that the scale level index s varies in a slightly redundant set. Once extracted, local extrema are quadratically interpolated this is very important especially at the sxechat resolution scales in order to have accurate keypoint localization at the full resolution.
